Tom, did it come with clear plastic sheets, and did you put a clear plastic sheet over it? If not, in my experience that top layer will not kick. Something about the air/oxygen keeping it from kicking which is why they give you the clear, plastic sheet which shields the goo from the air while the UV allows it to kick. Packing tape works well in place of the clear plastic sheet -- so, I've heard -- easier to wrap rails and such. (Not sure why the test bead worked if my theory is correct).
